HORSESHOE-CALK.

Specification of Letters Patent.

Patented Mar. 10, 191.4.

Application filed June 7, 1913. Serial No. 772,290.

ing a point and a head adapted to be re Vceived in and fit into therecess, and a keeper coperating with the calk and the recess of saidhorseshoe to secure the calk against accidental displacement.

The object of the invention is to provide a simple strong and durablecalk for use with horseshoes and the like of different kinds to minimizeslipping on icy or wet pavements, which can be readily applied to thehorseshoe and removed therefrom, and which, when worn or injured, can bereadily replaced, which may be of different forms and sizes, and whichcannot be easily accidentally displaced regardless of the conditionsunder which it is used.

The invention consists in the combinations, eonstructions andarrangements herein described and claimed.

Reference is to be had to the accompanying drawings forming part of thisapplication in which similar reference characters indicate like parts inthe several views and in which- Figure l is a plan view of a horseshoehaving calks applied thereto, embodying my invention, Fig. 2 is aninverted plan view of the horseshoe showing the calks attached thereto,Fig. 3 is a transverse section on the line 3-3 of Fig. 2, Fig. 4 is asimilar view on the line 1--11 of Fig. 1, Fig. 5 is an elevation of oneform of the calk showing the same removed from the horseshoe, and Fig.(i is a side view of one of the keepers used in securing the calks tothe horseshoe.

Before proceeding with a more detailed explanation of my invention itshould be clearly understood that while I have shown for exampleherewith calks having points of certain form, this structural featurecan be altered as desirable or necessary. For instance the point of thecalk may present a serrated edge or may actually constitute a sharpenedpoint. Furthermore, while I have used for illustration a horseshoehaving both toe and heel calks applied thereto, if so desired, one orthe other only of these may be used.

Referring more particularly to the drawing, I have shown a horseshoe 10of the customary shape provided with inner and outer openings 11 toreceive the horseshoe nails which serve to attach it to the hoof of theanimal. At the toe of the horseshoe, and near each of the heel endsthereof, are provided openings respectively '12 and 13. Of these theformer is of elongated shape and the latter are substantially square.The toeealk 14 has a part 15 of tapered cross section forming the pointof the calk, and has a hook-shaped head 16 curved forwardly anddownwardly, presenting at the front a rounded concavity 17 extendinglongitudinally of the calk, and having at the back a rearwardlyextending rib 18 formed at the Junction of the point and the head of thecalk. The openings 13 have at the rear lower edge a longitudinal recess19 designed to receive the rib 18. At the front it has a roundedlongitudinal flange 20, which is formed and proportioned to lit in theconcavity 17 under the downwardly directed lip 21 of the head 16. At theback the opening has a rounded face 29. which rests against thecorrespondingly rounded rear surface of the head 16 when the latter isdisposed within the opening, as shown in Fig. Ll. The flange 20 forms atthe front of the openings 13 a vgroove 23 in which the lip Q1 seats. Theparts are so proportioned that the head 16 of the calk can be insertedin the opening by an arcuate movement around the fiange 20. Underneaththe latter the horseshoe is cut away at 211 so that an opening is formedbetween the front of the calk and the lower forward edge of the opening13. The space so formed permits the insertion of the head of the calkand likewise is desired to receive the keeper 25. This is in effect atapered wedge of rounded cross section. It can be driven into theopening formed between the ealk and the horseshoe. The latter at bothsides of the opening 13 is cut away, at 26, to form slots or groovespermitting the insertion of the keeper. At the extremities 27 the ealkis longitudinally extended beyond the head 16 so that it will in effectseat against the under surface of the horseshoe at the sides of theopening 12, the head thus being smaller than the body of the calk, as isshown in Fig. 5.

The toe-calk is similar in every respect to the heel-calks alreadydescribed except as to dimensions. Itis of substantially elongated crosssection, as is shown in Figs. 1 and 2, and comprises a po-int 15a and ahookshaped head 16a. It is provided at the rear edge with a rib 18a andthe hook-shaped head terminates in a downwardly directed lip 21areceived in the groove 23a formed at the front of' the opening 12 by aflange 20a. The inner .surface 22a' of the recess 12 is rounded toreceive the correspondingly rounded back portion of the head 16a. At thefront lower edge the opening' 12 has a rounded cut away part 24a whichforms with the front of' the calk a space to receive the wedge-shapedkeeper 25a. The calk head has at the front the concavity 17a whichcorresponds to the concavity 17 of the calk la. Instead of extendinglongitudinally of the horseshoe as in the previous case the keeper 25ais disposed transversely thereof, the horseshoe having' a cut away part28 forming a groove to receive the keeper wedge. The toe-calk is, ofcourse, inserted in the recess provided for the purpose and is securedin this recess in the same manner as the heel-calks. I prefer to providethe openings 12 and 13 with peripheral rims and 30 respectively. Theseand other details of construction however, form no part of the inventionand may be varied as desirable or necessary.

The inner series of' openings will permit the shoe to be attached to asmaller hoof, thereby the same size of shoe can be used, within certainlimits, for different sizes of' hoofs.

I claim:

1. The combination with a horseshoe having a recess, ofl a calk having apoint and a hook-shaped head, said recess being provided with a flangeengaging under said hook-shaped head when the same is received in saidrecess, and a wedge-shaped keeper removably disposed between said headand the edge of said recess to secure said calk against displacement.

2. The combination with a horseshoe having a recess provided with aninwardly disposed flange, of' a calk having' a point and a hook-shapedhead adapted to be received in said recess and to embrace said' flange,and

a wedge-shaped keeper removably disposed between said flange and saidhead to secure said calk against displacement.

3. The combination with a horseshoe having a recess provided with aninwardly disposed lange, of a calk having a point and a hook-shaped headadapted to be received in said recess and to embrace said flange, and awedge-shaped keeper removably disposed between said flange and said headto secure said calk against displacement, said calk having at the rearedge a rib, said recess having a part formed'to receive said rib.

4. The combination with a horseshoe having a recess provided'with aninwardly disposed flange forming a groove, of a calk having a point anda hook-shaped head adapted to be received in said recess and to embracesaid flange, said head having a downwardly directed flange received insaid groove, said recess being cut away to form with said head of saidcalk an opening to receive a keeper, and a wedge-shaped keeper removablyreceived in said last-mentioned opening.

5. The combination with a horseshoe having a recess provided with aninwardly disposed flange forming a groove, of a calk having a point anda hook-shaped head adapted to be received in said recess and to embracesaid flange, said head having a downwardly directed flange received inysaid groove, said recess being cut away to form with said head of saidcalk an opening to receive a keeper, and a wedge-shaped keeper removablyreceived in said lastmentioned opening, said calk having at the rearedge a rib, said recess having-a part formed to receive saidvrib.

The combination with a horseshoe having a recess provided with a roundedflange extending longitudinally thereof, of a calk having a point and ahead of round hookshaped form adapted to embrace said flange, andprovided at the front with a concavity into which said flange will fitand a keeper for securing the calk in the recess fitting intermediatethe calk and the edge of the recess. v

In testimony whereof I have signed my name to this specification in thepresence of' two subscribing witnesses.
